To all whom it may concern.-

Be it known that I, ERIC W. PALMQUIST, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Body-l3olsters forRailway-Cars, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to a cast body-bolster for railway-cars which is ofU shape in transverse section, the sides of the bolster being tiedtogether at top byintegral webs, the upper faces of which are flush withthe top edges of the sides, my object being to provide a body-bolster ofthis shape that will be neat in appearance, as well as strong anddurable.

My invention consists in features of novelty 2o hereinafter fullydescribed, and pointed out in the claims.

Figure I is a top or plan View of myimproved body-bolster. Fig. II is abottom view. Fig. III is a view part in side elevation and part invertical section. Fig. IV is a vertical transverse section taken on lineIV IV, Fig. III.

The bolster has sides 2, a bottom 3, and outwardly-extending horizontalflanges 4 at the upper edges of the sides. The bottom extends upwardlyin both directions from the ce'nter,and itis provided with a centerbearing 5 and side bearings 6, the latter being located on the slopingsurfaces of the bottom. The. bottom is formed with openings 7 to lightenthe article.

The bolster is open at top except for integral webs 8, that tie thesides of the bolster together and which form rests for the trussrodstands, one of which is shown in dotted lines, Fig. III. The upper facesof these webs 40 are flush with the top edges of the bolster and withthe upper faces of the flanges 4, the Whole making a strong and durablebolster wherein the requisite amount of strength is combined withminimum weight. The webs 8 and flanges 4 provide firm supports for thetruss-rod stands, and the flanges provide firm supports for the timbersof the car-body.

I claim as my invention- 1. A cast body-bolster for railway-carsconsisting of sides having horizontally-extending flanges, a bottomprovided with center and side bearings, and webs that tie the sidestogether at the top, all formed integral, substantially as set forth.

2. A cast body-bolster for railway-cars consisting of sides havinghorizontally-extending flanges at their tops, a bottom inclined upwardlyeach Way from the center and having center and side bearings, and websthat tie the ()0 sides together at the top, all formed integral,substantially as set forth.

3. A cast body-bolster for railway-cars having a bottom and sides andprovided with integral webs flush with the top edges of the 65 sides andwhich tie the sides together and form supports for the truss-rod stands,substantially as set forth.
